If you have recently obtained a job but there are osha violations that make it hard for you to do it, should you tell?

Absolutely! Osha standards are for your protection. Not fully disclosing a violation puts you and your coworkers at risk. Do not be afraid to do the right thing.
Tell employer. Your employer may not know and may be happy to correct violations once advised. Also, employer cannot fire you for alerting him or her of such violations. Do it in a non-confrontational manner so employer doesn't become defensive.
